Opposition says Turnbull government must not fund new coal-fired power plants because they are not value for money

Labor is calling on the Turnbull government to create a national framework for the “orderly exit” of ageing power stations, with a transition plan for thousands of workers who will lose their jobs from station closures in coming years.

It also says the Turnbull government must stop funding new coal-fired power plants because commonwealth funding does not represent value for taxpayer dollars.

Evidence is growing that air turbulence is becoming stronger and more frequent because of climate change.

President Donald Trump is keeping some of his promises. Late last month he signed an executive order that tore up Barack Obama’s Clean Power Plan. Some commentators see this as putting the world on “the road to climate catastrophe”, while others have described it as an effort at “killing the international order”.

Will America lose out? Will China, which has chided Trump for selfishness, be the prime beneficiary as its solar panel industry continues to expand?

Here in Australia, in response to Trump’s order, Liberal backbencher Craig Kelly, chair of the government’s Environment Committee, took predictable aim at Australia’s international climate commitments, labelling the 2015 Paris Agreement “cactus”.

Kelly is on the record as disputing climate science and poured scorn on the Paris deal when it was struck. He is certainly not alone among the government’s ranks in this view.

The day after Trump’s election win last November, Australia ratified the Paris deal and Prime Minister Malcolm Turnbull said that it would take four years for Trump to pull out.

So is the Paris deal really “cactus”? What would we have lost if so? And does it matter?

What was agreed in Paris?

The Paris Agreement came after the United Nations Framework Convention on Climate Change (agreed at the Rio Earth Summit in 1992) had suffered a body blow at the 2009 UN climate talks in Copenhagen .

Opinion was divided on the reasons for the failure of the Copenhagen summit, but the then prime minister Kevin Rudd didn’t mince words in blaming the Chinese, infamously accusing them during the negotiations of trying to “rat-fuck us”. (For what it is worth, the British climate writer Mark Lynas agreed, albeit in less incendiary tones.)

A series of fence-mending meetings and careful smoothing of frayed nerves and wounded egos followed over the next five years. The French took charge and, with the price of renewable energy generation plummeting (and so making emissions reductions at least theoretically “affordable”), a deal was struck at the Paris summit in December 2015.

The agreement, notably silent on fossil fuels, calls on nations to take actions to reduce their emissions so that temperatures can be held to less than 2℃ above the pre-industrial average. This limit, which is not actually “safe”, will require a herculean effort and luck. If you add up all the national commitments, they will most likely take us to roughly 3℃ or beyond.

Australia’s commitment of a 26-28% reduction in greenhouse emissions by 2030, relative to 2005 levels, was seen as being at the low end of acceptable, and not enough to help meet the 2℃ limit.

Eminent climate scientist James Hansen labelled Paris a fraud, while Clive Spash (the economist monstered by Labor in 2009 for pointing out that Rudd’s Carbon Pollution Reduction Scheme was not much cop) thought it was worthless.

British climatologist Kevin Anderson is similarly dubious, arguing that the agreement assumes we will invent technologies that can suck carbon dioxide out of the atmosphere in, well, industrial quantities in the second half of this century.

So why the relative optimism among the climate commentariat? They’re desperate for a win after so many defeats, which stretch back all the way to the Kyoto climate conference of 1997.

Second time as farce?

After Australia’s initial promises to be a “good international citizen”, reality quickly set in during the early years of serious climate diplomacy.

Although Australia was an early ratifier of the treaty that emerged from the Rio summit, it nevertheless went to the first annual UN climate talks (chaired by a young Angela Merkel) determined to get a good deal for itself, as a country reliant on coal for electricity generation and eyeing big bucks from coal exports.

That meeting resulted in the “Berlin Mandate”, which called on developed nations to cut emissions first. Australia, gritting its teeth, agreed. Later that year the Keating Government released economic modelling (paid for in part by fossil fuel interests) which predicted economic Armageddon for Australia if a uniform emissions-reduction target was applied. This work was picked up by the new Howard government.

After much special pleading and swift footwork, Australia got two very sweet deals at Kyoto in 1997. First, its “reduction” target was 108% of 1990 levels within the 2008-12 period (the then environment minister Robert Hill reportedly refused to push for Howard’s preferred 118%).

Second, Australia successfully lobbied for a clause in the Kyoto treaty allowing reductions in land clearing to count as emissions reductions. This meant that Australia could bank benefits for things that were happening for entirely different reasons.

Australia signed the Kyoto Protocol in April 1998, but in September of the same year the cabinet decided not to ratify the deal unless the United States did. In March 2001 President George W. Bush pulled out, and Howard followed suit on World Environment Day in 2002.

Kyoto ratification then became a symbol of green virtue out of all proportion with its actual impact. Rudd got enormous kudos for ratifying it as his first official act as Prime Minister. And then reality set in again when he tried to actually implement an emissions-reduction policy.

Why does it matter?

Reality keeps on impinging. In a beautifully written piece in the New York Times, Ariel Dorfman lists disasters befalling Chile (readers in Queensland will feel like they know what he is on about). He concludes:

As we get ready to return to the United States, our friends and relatives ask, over and over, can it be true? Can President Trump be beset with such suicidal stupidity as to deny climate change and install an enemy of the earth as his environmental czar? Can he be so beholden to the blind greed of the mineral extraction industry, so ignorant of science, so monumentally arrogant, not to realize that he is inviting apocalypse? Can it be, they ask. The answer, alas, is yes.

Will the opinions of politicians like Donald Trump and Craig Kelly matter at all as long as the price of renewables keeps dropping? Well, possibly. “Shots across the bow” of renewables policy have in the past made investors nervous.

As Alan Pears on this website, and Giles Parkinson at Reneweconomy have explained, investors in electricity generation got spooked by the policy uncertainty caused by former prime minister Tony Abbott’s hostility to the Renewable Energy Target. That’s the real (and presumably intended) effect of statements like Kelly’s.

Will it work? Optimists will point to last week’s announcement that a $1bn solar farm will be built in South Australia, regardless of the concatenating Canberra catastrophe. Perennial pessimists will point to the Keeling Curve, which shows a remorseless and escalating rise in the level of atmospheric carbon dioxide. Time and prevailing politics are certainly not on our side.

Back-to-back severe bleaching events, caused by warming oceans, have affected two-thirds of Australia’s Great Barrier Reef, new aerial surveys have found. Climate change is not the only challenge – runoff-affected water quality, reef-killing crown of thorns starfish and the destruction of Cyclone Debbie also threaten the reef’s health. Scientists are warning that Australia has little time left to act on climate change and save the world’s largest living structure.

Coral bleaching has hit two-thirds of Australia's Great Barrier Reef within two years, surveys show.

NORTH DEVON: At the time of writing no oil from the Torrey Canyon has reached local beaches. On the other hand one has never had to look very far for oil waste in its coagulated state during recent years. It occurs in tiny pulverised fragments, indistinguishable from some of the constituents of shingle till it adheres to one’s foot, and in lumps up to the size of a football. The oiled carcass of a gannet or an auk is an only too familiar sight on the high water mark.

The Atlantic drift which brings oil on to our coastline also carries less objectionable material: seeds, skeletons and bodies of sea creatures, shells, many of which have travelled a very long distance. Among these are seed cases and fruit from trees which are native to the banks of the Amazon; the flat, purple Entada scandens, the Sacoglottis amazonica, Mucuna the fruit of a climbing plant; objects which are of the size of a marble or golf ball. At the other end of the scale whales and sharks in addition to ships are sometimes cast up. What appeared to its discoverers to be the exceptionally well-preserved bones of “an extinct prehistoric reptile” turned out to be the skeleton of a whale buried by locals, as the simplest method of disposing of its bulk, earlier in the century. And when an expert hurried out to inspect an “Elizabethan canon” uncovered by the tide, he found it to be the rusted end-section of an old sewer!

The big lie propagated by government and big business is that it is possible to turn things around for the reef without tackling global warming

Once upon a time, in the distant 60s and 70s, the Great Barrier Reef faced imminent destruction. Tenement applications for drilling and mining covered vast swathes of the reef, with both government and industry enthusiastically backing the plans for mass exploitation.

In the face of the reef’s impending doom a motley collection of ordinary Australians shared a common determination that something had to be done. But the odds didn’t look good. The poet turned campaigner Judith Wright wrote that “if it had not been for the public backing for protection of the reef that we knew existed, we might have given up hope”.
